Antimicrobial mixtures comprising at least one hydroxyphenone derivative

ABSTRACT

Suggested is a synergistic antimicrobial mixture comprising a hydroxyacetophenone and one additional antimicrobial agent. The mixture is particular useful for fighting  Aspergillus brasiliensis.

AREA OF INVENTION

The present invention belongs to the area of antimicrobial agents for personal care, detergent and nutrition products and refers to new antimicrobial agents and their use in various areas of consumer products.

BACKGROUND OF THE INVENTION

In the cosmetics and pharmaceutical and in the foodstuffs industry there is a constant need for agents having antimicrobial properties, in particular for the preservation of products which are otherwise perishable (such as e.g. cosmetics, pharmaceutical products or foodstuffs), but also for direct cosmetic or therapeutic treatment of microorganisms which can have an adverse influence on the human or animal body. Reference may be made by way of example to microorganisms which can cause body odour, acne, mycoses or the like.

In the technical fields referred to a large number of antimicrobial active compounds are indeed already employed, but alternatives nevertheless continue to be sought, in order to be able to perform targeted specific treatments and/or reduce side effects. In this context, however, in the search for alternative agents having an antimicrobial and in particular preserving action it is to be noted that the substances used in the cosmetics, pharmaceutical and/or foodstuffs field must be

-   -   toxicologically acceptable     -   readily tolerated by the skin     -   stable (in particular in the conventional cosmetic and/or         pharmaceutical formulations)     -   largely and preferably completely odourless     -   inexpensive to prepare (i.e. employing standard processes and/or         starting from standard precursors)     -   easy to formulate (i.e. preferably liquid) and should not be         detrimental to the final product.

Furthermore, they should have antimicrobial activity characteristics, which fulfill the diverse criteria. They should

-   -   provide a broad-spectrum anti-microbial activity against gram         positive and gram negative bacteria, yeast and mould     -   show a particularly strong activity against the mould A.         brasiliensis     -   be active in different cosmetic formulations at different pH         values.

RELATED PRIOR ART

From the state of the art numerous publications are known dealing with various types of products that are active against micro-organisms. For example, Schenk et al. evaluated different fungicides for preservation of moist alfalfa hay (Laboratory evaluation of fungicides for the preservation of moist hay). 4-hydroxyacetophenone was among the compounds tested, but was found to not prevent mold growth and therefore not suitable for hay preservation. Applications in cosmetic formulations are not disclosed (Agronomy Journal, 47, 64-69, 1955).

Zauner et al. published impurities of beet molasses that inhibited the respiration and fermentation of the yeast Saccharomyces cerevisiae (Inhibitory activity of impurities of beet molasses and plant protectants on yeast (Saccharomyces cerevisiae) respiration and fermentation.) No other microorganisms than S. cerevisiae were investigated, particularly, not molds or bacteria. No reference to potential use of the inhibitory substances in the field of cosmetics is given (Brantweinwirtschaft, 119(9), 154-6, 158-60, 163, 1979).

Hirvi et al. investigated the composition of cranberry aroma and found 4-hydroxy-aceto-phenone as one constituent. No antimicrobial activity of cranberry aroma or any of its constituents are mentioned (Zeitschrift für Lebensmittel-Untersuchung und-Forschung, 172(5), 365-7, 1981).

Alvarez et al. studied the anti-inflammatory properties of different constituents of the plant Lampaya hieronymi. 4-hydroxyacetophenone was one of the active compounds reducing subcutaneous inflammation when administered intraperitoneally. The agents were not applied topically and no data on antimicrobial activity are disclosed for any of the presented compounds (II Farmaco, 55, 502-5, 2000).

Schmeda-Hirschmann et al. identified constituents of Tagetes mendocina revealing antioxidant activity in a chemical in vitro assay. Among others, 4-hydroxyacetophenone proved to be one of the active constituents. No data on antimicrobial activity and no application for cosmetics are disclosed for any of the presented compounds (Zeitschrift für Naturforschung, 59c, 345-353, 2004).

In this context also reference is made to DE-OS 3629056 (Celamerck) discloses the extraction of substance mixtures, including p-hydroxyacetophenone, from the cuticula of spruce needles using apolar solvents. These substance mixtures are claimed to be effective to counteract phytopathogenic fungi, i.e. Cladosporium cucumerinum and Rhizosphaera kalkhoffii. No other microorganisms, e.g. the non-phytopathogenic yeast C. albicans or bacteria are included. Furthermore, no specific application, such as product preservation of cosmetic formulations is mentioned.

US 2008/0254130 AA (Bioderm Research) discloses a topical method of treatment of dysfunction of certain dermal enzymes and the treatment of skin condition or disorder caused by said dysfunction. No antimicrobial activity of the different acetophenone derivatives is described.

JP 07 206645 A (POLA) discloses acetophenone derivatives as hair growth agents. No antimicrobial activity of the different acetophenone derivatives is described.

EP 2774481 B1 (SYMRISE) suggests antimicrobial compositions comprising (a) at least one acetophenone derivative of formula (I) in which R1 stands for hydrogen or methyl, and R2 stands for hydrogen, hydroxyl or a —OCH3 group, or a cosmetically or pharmaceutically acceptable salt thereof, and (b) at least one second antimicrobial agent. However, it turned out that synergistic effects between components (a) and (b) are not always significant and strongly depend on weight ratios.

Problem to be Solved

The search for suitable (active) substances, which have one or more of the properties mentioned to an adequate extent is made difficult for the person skilled in the art in that there is no clear dependency between the chemical structure of a substance on the one hand and its biological activity against certain microorganisms (bacteria, yeast, fungi, small eukaryotes) on the other hand. This makes testing of substances in laboratory experiments inevitable. In addition, the antimicrobial performance in cosmetic formulation cannot be derived from standard anti-microbial screening tests, such as growth inhibition experiments as described in e.g. DIN 58940 or ISO 20776. Many antimicrobial substances characterized by low minimum inhibitory concentrations (MICs) fail to perform in more advanced and applied assays. For product preservation, the highly laborious and time-consuming “challenge test” according to ISO 11930, European Pharmacopoeia 7-5.1.3, or United States Pharmacopoeia 35 has to be used. Furthermore, there is no predictable connection between the chemical structure and other physico-chemical parameters relevant to the field of cosmetics, i.e. the toxicological acceptability, the skin tolerability, the stability, solubility and formulation properties and the smell of a substance.

Therefore, the problem underlying the present invention has been developing new antimicrobial agents that fulfils the complex profile explained above and is particularly active at low concentrations against a variety of different micro-organisms. Another object of the invention has been providing emulsions comprising such antimicrobial agents with improved stability.

-   -   and their mixtures.

The invention is based on the surprising finding that compounds of formula (I) according to the invention show a very good broad spectrum activity as agent to preserve various formulations against microbial spoilage. Furthermore, compounds of formula (I) synergistically intensified antimicrobial effects at least against selected microorganisms, in particular against mould species of the genus Aspergillus, such as Aspergillus brasiliensis, niger, flavus, fumigatus and also other microorganisms. Moulds are known to be combated only with great difficulty, due to their high tolerance for different pH, temperature, osmotic pressure and nutrient conditions as well as their ability to resist to and degrade different chemicals.

In particular, it has been found that the mixtures according to the invention can be used outstandingly as an antimicrobial active compound mixture, in particular for preserving otherwise perishable articles.

More particularly it was found that the synergistically active mixtures according to the invention have a good action against Staphylococcus epidermidis, Corynebacterium xerosis, Brevibacterium epidermidis, Propionibacterium acnes and against Trichophyton and Epidermophyton species, so that they can be employed as agents for the treatment or the combating of underarm and foot odour or body odour generally, as agents for combating acne, as anti-dandruff agents and for the treatment of mycoses, in particular dermatomycoses.

Acetophenone Derivatives

Acetophenone derivatives according to the present invention represent known compounds that can be obtained by ordinary methods of organic chemistry. It is understood that both substituents OR₁ and R₂ can be located in ortho, meta or para position towards the methylketo group.

Preferably, the species are selected from the group consisting of

or their mixtures. In as far the definition refers to cosmetically or pharmaceutically acceptable salts of said derivatives, this means that these salts can be safely used for pharmaceutical purposes. This does not mean that the present invention or any aspect thereof is restricted to the use of a compound of formula (I) or a corresponding mixture for pharmaceutical purposes. Generally, if a salt can be used for pharmaceutical purposes it can likewise be used for cosmetic purposes, or in food or beverage formulations. In particular, the sodium and potassium and ammonium salts of compounds of formula (I) are considered as (pharmaceutically) acceptable salts. In some cases the utilization of the respective ionic compound or solvate carrier proves to be superior to the unmodified derivative. The (pharmaceutically) acceptable salts (and the corresponding solvates) of compounds of formula (I) can be prepared by standard procedures. Hereinafter, any reference to a compound of formula (I) or a corresponding mixture as defined above is to be understood as comprising an additional reference to corresponding (pharmaceutically) acceptable salts thereof.

It is also worth to be mentioned that although persons skilled in the art have already addressed the antimicrobial properties of aromatic alcohols, such as e.g. benzyl alcohol, 2-phenylethyl alcohol, 3-Phenylpropanol, 2-phenoxyethanol, 3-phenoxypropanol, 1-phenoxy-propan-2-ol, 3-phenoxy-propane-1,2-diol, benzyloxymethanol and (benzyloxymethoxy)-methanol extensively, there has hitherto been no indication that mixtures of the acetophenone derivatives have a significantly improved antimicrobial action (at least against selected microorganisms) in the individual case. It was therefore particularly surprising that the mixtures according to the invention show a highly synergistic activity, and in the treatment moulds of the genus Aspergillus are significantly superior to

-   -   individually dosed compounds of the formula (I) or     -   individually dosed further antimicrobially active compounds not         being compounds of formula (I), in particular individually dosed         diols and aromatic alcohols, such as e.g. 1,3-propanediol,         methyl propanediol, 1,2-pentanediol, 1,2-hexanediol,         1,2-octanediol, ethylhexylglycerin, hexoxy-propan-1,2-diol,         heptoxy-propan-1,2-diol, octoxy-propan-1,2-diol,         3-benzyloxy-propan-1,2-diol, 3-phenylethyloxy-propan-1,2-diol,         3-phenylpropyloxy-propan-1,2-diol,         3-methylbenzyloxy-propan-1,2-diol, 3-phenyl propanol,         2-phenoxyethanol and mixtures of these compounds         at the same concentration, in particular in respect of the         reduction in microbial counts and the speed of the reduction in         microbial count.

In a preferred embodiment the antimicrobial agent comprises or contains two or three of the compounds (Ia), (Ib) and (Ic), as for example 2-hydroxyacetophenone and 3-hydroxyacetophenone, or 2-hydroxyacetophenone and 4-hydroxyacetophenone, or 3-hydroxyacetophenone and 4-hydroxyacetophenone.

The mixtures may contain components (a) and (b) in a weight ratio of about 1:99 to about 99:1, preferably about 20:80 to about 80:20 and more preferably about 40:60 to about 60:40.

Suitable enzyme inhibitors are, for example, esterase inhibitors. These are preferably trialkyl citrates, such as trimethyl citrate, tripropyl citrate, triisopropyl citrate, tributyl citrate and, in particular, triethyl citrate (Hydagen CAT). The substances inhibit enzyme activity, thereby reducing the formation of odour.

Odour Absorbers and Antiperspirant Active Agents

Suitable odour absorbers are substances which are able to absorb and largely retain odour-forming compounds. They lower the partial pressure of the individual components, thus also reducing their rate of diffusion. It is important that perfumes must remain unimpaired in this process. Odour absorbers are not effective against bacteria. They comprise, for example, as main constituent, a complex zinc salt of ricinoleic acid or specific, largely odour-neutral fragrances which are known to the person skilled in the art as “fixatives”, such as, for example, extracts of labdanum or styrax or certain abietic acid derivatives. The odour masking agents are fragrances or perfume oils, which, in addition to their function as odour masking agents, give the deodorants their respective fragrance note. Perfume oils which may be mentioned are, for example, mixtures of natural and synthetic fragrances. Natural fragrances are extracts from flowers, stems and leaves, fruits, fruit peels, roots, woods, herbs and grasses, needles and branches, and resins and balsams. Also suitable are animal products, such as, for example, civet and castoreum. Typical synthetic fragrance compounds are products of the ester, ether, aldehyde, ketone, alcohol, and hydrocarbon type. Fragrance compounds of the ester type are, for example, benzyl acetate, p-tert-butylcyclohexyl acetate, linalyl acetate, phenylethyl acetate, linalyl benzoate, benzyl formate, allyl cyclohexylpropionate, styrallyl propionate and benzyl salicylate. The ethers include, for example, benzyl ethyl ether, and the aldehydes include, for example, the linear alkanals having 8 to 18 carbon atoms, citral, citronellal, citronellyloxyacetaldehyde, cyclamen aldehyde, hydroxycitronellal, lilial and bourgeonal, the ketones include, for example, the ionones and methyl cedryl ketone, the alcohols include anethole, citronellol, eugenol, isoeugenol, geraniol, linaool, phenylethyl alcohol and terpineol, and the hydrocarbons include mainly the terpenes and balsams. Preference is, however, given to using mixtures of different fragrances which together produce a pleasing fragrance note. Essential oils of relatively low volatility, which are mostly used as aroma components, are also suitable as perfume oils, e.g. sage oil, camomile oil, oil of cloves, melissa oil, mint oil, cinnamon leaf oil, linden flower oil, juniperberry oil, vetiver oil, olibanum oil, galbanum oil, labdanum oil and lavandin oil. Preference is given to using bergamot oil, dihydromyrcenol, lilial, lyral, citronellol, phenylethyl alcohol, α-hexylcinnamaldehyde, geraniol, benzylacetone, cyclamen aldehyde, linalool, boisambrene forte, ambroxan, indole, hedione, sandelice, lemon oil, mandarin oil, orange oil, allyl amyl glycolate, cyclovertal, lavandin oil, clary sage oil, β-damascone, geranium oil bourbon, cyclohexyl salicylate, Vertofix coeur, iso-E-super, Fixolide NP, evernyl, iraldein gamma, phenylacetic acid, geranyl acetate, benzyl acetate, rose oxide, romilat, irotyl and floramat alone or in mixtures.

Preferred compositions according to the present inventions are selected from the group of products for treatment, protecting, care and cleansing of the skin and/or hair or as a make-up product, preferably as a leave-on product (meaning that the one or more compounds of formula (I) stay on the skin and/or hair for a longer period of time, compared to rinse-off products, so that the moisturizing and/or anti-ageing and/or wound healing promoting action thereof is more pronounced).

The formulations according to the invention are preferably in the form of an emulsion, e.g. W/O (water-in-oil), O/W (oil-in-water), W/O/W (water-in-oil-in-water), O/W/O (oil-in-water-in-oil) emulsion, PIT emulsion, Pickering emulsion, emulsion with a low oil content, micro- or nanoemulsion, a solution, e.g. in oil (fatty oils or fatty acid esters, in particular C₆-C₃₂ fatty acid C₂-C₃₀ esters) or silicone oil, dispersion, suspension, creme, lotion or milk, depending on the production method and ingredients, a gel (including hydrogel, hydrodispersion gel, oleogel), spray (e.g. pump spray or spray with propellant) or a foam or an impregnating solution for cosmetic wipes, a detergent, e.g. soap, synthetic detergent, liquid washing, shower and bath preparation, bath product (capsule, oil, tablet, salt, bath salt, soap, etc.), effervescent preparation, a skin care product such as e.g. an emulsion (as described above), ointment, paste, gel (as described above), oil, balsam, serum, powder (e.g. face powder, body powder), a mask, a pencil, stick, roll-on, pump, aerosol (foaming, non-foaming or post-foaming), a deodorant and/or antiperspirant, mouthwash and mouth rinse, a foot care product (including keratolytic, deodorant), an insect repellent, a sunscreen, aftersun preparation, a shaving product, aftershave balm, pre- and aftershave lotion, a depilatory agent, a hair care product such as e.g. shampoo (including 2-in-1 shampoo, anti-dandruff shampoo, baby shampoo, shampoo for dry scalps, concentrated shampoo), conditioner, hairtonic, hairwater, hair rinse, styling creme, pomade, perm and setting lotion, hair spray, styling aid (e.g. gel or wax), hair smoothing agent (detangling agent, relaxer), hair dye such as e.g. temporary direct-dyeing hair dye, semi-permanent hair dye, permanent hair dye, hair conditioner, hair mousse, eye care product, make-up, make-up remover or baby product.

The formulations according to the invention are particularly preferably in the form of an emulsion, in particular in the form of a W/O, O/W, W/O/W, O/W/O emulsion, PIT emulsion, Pickering emulsion, emulsion with a low oil content, micro- or nanoemulsion, a gel (including hydrogel, hydrodispersion gel, oleogel), a solution e.g. in oil (fatty oils or fatty acid esters, in particular C₆-C₃₂ fatty acid C₂-C₃₀ esters)) or silicone oil, or a spray (e.g. pump spray or spray with propellant).

Auxiliary substances and additives can be included in quantities of 5 to 99% b.w., preferably 10 to 80% b.w., based on the total weight of the formulation. The amounts of cosmetic or dermatological auxiliary agents and additives and perfume to be used in each case can easily be determined by the person skilled in the art by simple trial and error, depending on the nature of the particular product.

The preparations can also contain water in a quantity of up to 99% b.w., preferably 5 to 80% b.w., based on the total weight of the preparation.

Detergent Compositions

Another embodiment of the present invention covers a detergent composition comprising a working amount of at least one acetophenone derivative or its mixtures with additional preservatives and/or antimicrobial agents, which might be present in amounts of from about 0.01 to about 10, preferably about 0.05 to about 5 and more preferably about 0.1 to about 1% b.w.—calculated on the total composition.

The detergent compositions according to the present invention may comprise any of the ingredients customarily found in such compositions, such as, for example, anionic, nonionic, cationic, amphoteric or zwitterionic (co-)surfactants, organic solvents, builders, enzymes and additional auxiliaries such as soil repellents, thickeners, colorants and fragrances or the like.

Anionic Co-Surfactants

Preferably, surfactants of the sulfonate type, alk(en)yl sulfonates, alkoxylated alk(en)yl sulfates, ester sulfonates and/or soaps are used as the anionic surfactants. Suitable surfactants of the sulfonate type are advantageously C₉₋₁₃ alkylbenzene sulfonates, olefin sulfonates, i.e. mixtures of alkene- and hydroxyalkane sulfonates, and disulfonates, as are obtained, for example, by the sulfonation with gaseous sulfur trioxide of C₁₂₋₁₈ monoolefins having a terminal or internal double bond and subsequent alkaline or acidic hydrolysis of the sulfonation products.

Alk(en)yl sulfates. Preferred alk(en)yl sulfates are the alkali and especially the sodium salts of the sulfuric acid half-esters of the C₁₂-C₁₈ fatty alcohols, for example, from coconut butter alcohol, tallow alcohol, lauryl, myristyl, cetyl or stearyl alcohol or from C₈-C₂₀ oxo alcohols and those half-esters of secondary alcohols of these chain lengths. Alk(en)yl sulfates of the cited chain lengths that comprise a synthetic straight chain alkyl group manufactured petrochemically are also preferred. The C₁₂-C₁₆ alkyl sulfates and C₁₂-C₁₅ alkyl sulfates as well as C₁₄-C₁₅ alkyl sulfates and C₁₄-C₁₆ alkyl sulfates are particularly preferred on the grounds of laundry performance. The 2,3-alkyl sulfates, which can be obtained from Shell Oil Company under the trade name DAN™, are also suitable anionic surfactants.

Alk(en)yl ether sulfates. Sulfuric acid mono-esters derived from straight-chained or branched C₇-C₂₁ alcohols ethoxylated with 1 to 6 moles ethylene oxide are also suitable, such as 2-methyl-branched C₉-C₁₁ alcohols with an average of 3.5 mol ethylene oxide (EO) or C₁₂-C₁₈ fatty alcohols with 1 to 4 EO.

Ester sulfonates. The esters of alpha-sulfo fatty acids (ester sulfonates), e.g., the alpha-sulfonated methyl esters of hydrogenated coco-, palm nut- or tallow acids are likewise suitable.

Soaps. Soaps, in particular, can be considered as further anionic surfactants. Saturated fatty acid soaps are particularly suitable, such as the salts of lauric acid, myristic acid, palmitic acid, stearic acid, hydrogenated erucic acid and behenic acid, and especially soap mixtures derived from natural fatty acids such as coconut oil fatty acid, palm kernel oil fatty acid or tallow fatty acid. Those soap mixtures are particularly preferred that are composed of 50 to 100 wt. % of saturated C₁₂-C₂₄ fatty acid soaps and 0 to 50 wt. % of oleic acid soap.

Ether carboxylic acids. A further class of anionic surfactants is that of the ether carboxylic acids, obtainable by treating fatty alcohol ethoxylates with sodium chloroacetate in the presence of basic catalysts. They have the general formula: RO(CH₂CH₂O)_(p)CH₂COOH with R=C₁-C₁₈ and p=0.1 to 20. Ether carboxylic acids are insensitive to water hardness and possess excellent surfactant properties.

Nonionic (Co-)Surfactants

Alkohol alkoxylates. The added nonionic surfactants are preferably alkoxylated and/or propoxylated, particularly primary alcohols having preferably 8 to 18 carbon atoms and an average of 1 to 12 mol ethylene oxide (EO) and/or 1 to 10 mol propylene oxide (PO) per mol alcohol. C₈-C₁₆-Alcohol alkoxylates, advantageously ethoxylated and/or propoxylated C₁₀-C₁₅-alcohol alkoxylates, particularly C₁₂-C₁₄ alcohol alkoxylates, with an ethoxylation degree between 2 and 10, preferably between 3 and 8, and/or a propoxylation degree between 1 and 6, preferably between 1.5 and 5, are particularly preferred. The cited degrees of ethoxylation and propoxylation constitute statistical average values that can be a whole or a fractional number for a specific product. Preferred alcohol ethoxylates and propoxylates have a narrowed homolog distribution (narrow range ethoxylates/propoxylates, NRE/NRP). In addition to these nonionic surfactants, fatty alcohols with more than 12 EO can also be used. Examples of these are (tallow) fatty alcohols with 14 EO, 16 EO, 20 EO, 25 EO, 30 EO or 40 EO.

Alkylglycosides (APG®). Furthermore, as additional nonionic surfactants, alkyl glycosides that satisfy the general Formula RO(G)_(x), can be added, e.g., as compounds, particularly with anionic surfactants, in which R means a primary linear or methyl-branched, particularly 2-methyl-branched, aliphatic group containing 8 to 22, preferably 12 to 18 carbon atoms and G stands for a glycose unit containing 5 or 6 carbon atoms, preferably for glucose. The degree of oligomerization x, which defines the distribution of monoglycosides and oligoglycosides, is any number between 1 and 10, preferably between 1.1 and 1.4.

Fatty acid ester alkoxylates. Another class of preferred nonionic surfactants, which are used either as the sole nonionic surfactant or in combination with other nonionic surfactants, in particular, together with alkoxylated fatty alcohols and/or alkyl glycosides, are alkoxylated, preferably ethoxylated or ethoxylated and propoxylated fatty acid alkyl esters preferably containing 1 to 4 carbon atoms in the alkyl chain, more particularly the fatty acid methyl esters which are described, for example, in Japanese Patent Application JP-A-58/217598 or which are preferably produced by the process described in International Patent Application WO-A-90/13533. Methyl esters of C₁₂-C₁₈ fatty acids containing an average of 3 to 15 EO, particularly containing an average of 5 to 12 EO, are particularly preferred.

Amine oxides. Nonionic surfactants of the amine oxide type, for example, N-coco alkyl-N,N-dimethylamine oxide and N-tallow alkyl-N,N-dihydroxyethylamine oxide, and the fatty acid alkanolamides may also be suitable. The quantity in which these nonionic surfactants are used is preferably no more than the quantity in which the ethoxylated fatty alcohols are used and, particularly no more than half that quantity.

Gemini surfactants. The so-called gemini surfactants can be considered as further surfactants. Generally speaking, such compounds are understood to mean compounds that have two hydrophilic groups and two hydrophobic groups per molecule. As a rule, these groups are separated from one another by a “spacer”. The spacer is usually a hydrocarbon chain that is intended to be long enough such that the hydrophilic groups are a sufficient distance apart to be able to act independently of one another. These types of surfactants are generally characterized by an unusually low critical micelle concentration and the ability to strongly reduce the surface tension of water. In exceptional cases, however, not only dimeric but also trimeric surfactants are meant by the term gemini surfactants. Suitable gemini surfactants are, for example, sulfated hydroxy mixed ethers according to German Patent Application DE 4321022 A1 or dimer alcohol bis- and trimer alcohol tris sulfates and ether sulfates according to International Patent Application WO 96/23768 A1. Blocked end group dimeric and trimeric mixed ethers according to German Patent Application DE 19513391 A1 are especially characterized by their bifunctionality and multifunctionality. Gemini polyhydroxyfatty acid amides or polyhydroxyfatty acid amides, such as those described in International Patent Applications WO 95/19953 A1, WO 95/19954 A1 and WO 95/19955 A1 can also be used.

Cationic (Co)-Surfactants

Tetraalkyl ammonium salts. Cationically active surfactants comprise the hydrophobic high molecular group required for the surface activity in the cation by dissociation in aqueous solution. A group of important representatives of the cationic surfactants are the tetraalkyl ammonium salts of the general formula: (R¹R²R³R⁴N⁺) X⁻. Here R1 stands for C₁-C₈ alk(en)yl, R², R³ and R⁴, independently of each other, for alk(en)yl radicals having 1 to 22 carbon atoms. X is a counter ion, preferably selected from the group of the halides, alkyl sulfates and alkyl carbonates. Cationic surfactants, in which the nitrogen group is substituted with two long acyl groups and two short alk(en)yl groups, are particularly preferred.

Esterquats. A further class of cationic surfactants particularly useful as co-surfactants for the present invention is represented by the so-called esterquats. Esterquats are generally understood to be quaternised fatty acid triethanolamine ester salts. These are known compounds which can be obtained by the relevant methods of preparative organic chemistry. Reference is made in this connection to International patent application WO 91/01295 A1, according to which triethanolamine is partly esterified with fatty acids in the presence of hypophosphorous acid, air is passed through the reaction mixture and the whole is then quaternised with dimethyl sulphate or ethylene oxide. In addition, German patent DE 4308794 C1 describes a process for the production of solid esterquats in which the quaternisation of triethanolamine esters is carried out in the presence of suitable dispersants, preferably fatty alcohols.

Typical examples of esterquats suitable for use in accordance with the invention are products of which the acyl component derives from monocarboxylic acids corresponding to formula RCOOH in which RCO is an acyl group containing 6 to 10 carbon atoms, and the amine component is triethanolamine (TEA). Examples of such monocarboxylic acids are caproic acid, caprylic acid, capric acid and technical mixtures thereof such as, for example, so-called head-fractionated fatty acid. Esterquats of which the acyl component derives from monocarboxylic acids containing 8 to 10 carbon atoms, are preferably used. Other esterquats are those of which the acyl component derives from dicarboxylic acids like malonic acid, succinic acid, maleic acid, fumaric acid, glutaric acid, sorbic acid, pimelic acid, azelaic acid, sebacic acid and/or dodecanedioic acid, but preferably adipic acid. Overall, esterquats of which the acyl component derives from mixtures of monocarboxylic acids containing 6 to 22 carbon atoms, and adipic acid are preferably used. The molar ratio of mono and dicarboxylic acids in the final esterquat may be in the range from 1:99 to 99:1 and is preferably in the range from 50:50 to 90:10 and more particularly in the range from 70:30 to 80:20. Besides the quaternised fatty acid triethanolamine estersalts, othersuitable esterquats are quaternized estersalts of mono-/dicarboxylic acid mixtures with diethanolalkyamines or 1,2-dihydroxypropyl dialkylamines. The esterquats may be obtained both from fatty acids and from the corresponding triglycerides in admixture with the corresponding dicarboxylic acids. One such process, which is intended to be representative of the relevant prior art, is proposed in European patent EP 0750606 B1. To produce the quaternised esters, the mixtures of mono- and dicarboxylic acids and the triethanolamine—based on the available carboxyl functions—may be used in a molar ratio of 1.1:1 to 3:1. With the performance properties of the esterquats in mind, a ratio of 1.2:1 to 2.2:1 and preferably 1.5:1 to 1.9:1 has proved to be particularly advantageous. The preferred esterquats are technical mixtures of mono-, di- and triesters with an average degree of esterification of 1.5 to 1.9.

Amphoteric or Zwitterionic Co-Surfactants

Betaines. Amphoteric or ampholytic surfactants possess a plurality of functional groups that can ionize in aqueous solution and thereby—depending on the conditions of the medium—lend anionic or cationic character to the compounds (see DIN 53900, July 1972). Close to the isoelectric point (around pH 4), the amphoteric surfactants form inner salts, thus becoming poorly soluble or insoluble in water. Amphoteric surfactants are subdivided into ampholytes and betaines, the latter existing as zwitterions in solution. Ampholytes are amphoteric electrolytes, i.e. compounds that possess both acidic as well as basic hydrophilic groups and therefore behave as acids or as bases depending on the conditions. Especially betaines are known surfactants which are mainly produced by carboxyalkylation, preferably carboxymethylation, of amine compounds. The starting materials are preferably condensed with halocarboxylic acids or salts thereof, more particularly sodium chloroacetate, one mole of salt being formed per mole of betaine. The addition of unsaturated carboxylic acids, such as acrylic acid for example, is also possible. Examples of suitable betaines are the carboxy alkylation products of secondary and, in particular, tertiary amines which correspond to formula R¹R²R³N—(CH₂)_(q)COOX where R¹ is a an alkyl radical having 6 to 22 carbon atoms, R² is hydrogen or an alkyl group containing 1 to 4 carbon atoms, R³ is an alkyl group containing 1 to 4 carbon atoms, q is a number of 1 to 6 and X is an alkali and/or alkaline earth metal or ammonium. Typical examples are the carboxymethylation products of hexylmethylamine, hexyldimethylamine, octyldimethylamine, decyldimethylamine, C_(12/14)-cocoalkyldimethylamine, myristyldimethylamine, cetyldimethylamine, stearyldimethylamine, stearylethylmethylamine, oleyldimethylamine, C_(1/18)-tallowalkyldimethylamine and their technical mixtures, and particularly dodecyl methylamine, dodecyl dimethylamine, dodecyl ethylmethylamine and technical mixtures thereof.

Alkylamido betaines. Other suitable betaines are the carboxyalkylation products of amidoamines corresponding to formula R¹CO(R³)(R⁴)—NH—(CH₂)_(p)—N—(CH₂)_(q)COOX in which R¹CO is an aliphatic acyl radical having 6 to 22 carbon atoms and 0 or 1 to 3 double bonds, R² is hydrogen or an alkyl radical having 1 to 4 carbon atoms, R³ is an alkyl radical having 1 to 4 carbon atoms, p is a number from 1 to 6, q is a number from 1 to 3 and X is an alkali and/or alkaline earth metal or ammonium. Typical examples are reaction products of fatty acids having 6 to 22 carbon atoms, like for example caproic acid, caprylic acid, caprinic acid, lauric acid, myristic acid, palmitic acid, palmoleic acid, stearic acid, isostearic acid, oleic acid, elaidic acid, petroselinic acid, linolic acid linoleic acid, elaeostearic acid, arachidonic acid, gadoleic acid, behenic acid, erucic acid and their technical mixtures with N,N-dimethylaminoethylamine, N,N-dimethylaminopropylamine, N,N-diethylaminoethylamine und N,N-diethylaminopropylamine, which are condensed with sodium chloroacetate. The commercially available products include Dehyton® K and Dehyton® PK (Cognis Deutschland GmbH & Co., KG) as well as Tego® Betaine (Goldschmidt).

Imidazolines. Other suitable starting materials for the betaines to be used for the purposes of the invention are imidazolines. These substances are also known and may be obtained, for example, by cyclizing condensation of 1 or 2 moles of C₆-C₂₂ fatty acids with poly-functional amines, such as for example aminoethyl ethanolamine (AEEA) or diethylenetriamine. The corresponding carboxyalkylation products are mixtures of different open-chain betaines. Typical examples are condensation products of the above-mentioned fatty acids with AEEA, preferably imidazolines based on lauric acid, which are subsequently betainised with sodium chloroacetate. The commercially available products include Dehyton® G (Cognis Deutschland GmbH & Co., KG)

The amount of (co-)surfactant comprised in the inventive compositions is advantageously 0.1 wt. % to 90 wt. %, particularly 10 wt. % to 80 wt. % and particularly preferably 20 wt. % to 70 wt.-%.

Organic Solvent

Liquid light or heavy duty detergents may comprise organic solvents, preferably those miscible with water. Polydiols, ethers, alcohols, ketones, amides and/or esters are preferably used as the organic solvent for this in amounts of 0 to 90 wt. %, preferably 0.1 to 70 wt. %, particularly 0.1 to 60 wt. %. Low molecular weight polar substances, such as for example, methanol, ethanol, propylene carbonate, acetone, acetonylacetone, diacetone alcohol, ethyl acetate, 2-propanol, ethylene glycol, propylene glycol, glycerin, diethylene glycol, dipropylene glycol monomethyl ether and dimethylformamide or their mixtures are preferred.

Enzymes

Suitable enzymes include, in particular, those from the classes of hydrolases, such as proteases, esterases, lipases or lipolytic enzymes, amylases, cellulases or other glycosyl hydrolases and mixtures thereof. In the wash, all these hydrolases contribute to removing stains such as protein, fat or starchy stains and against graying. Moreover, cellulases and other glycosyl hydrolases can contribute to increased softness of the textile and to color retention by removing pilling and micro fibrils. Oxidoreductases can also be added to the bleaches or to inhibit the color transfer. Enzymatic active materials obtained from bacterial sources or fungi such as Bacillus subtilis, Bacillus licheniformis, Streptomyceus griseus and Humicola insolens are particularly well suited. Proteases of the subtilisin type and particularly proteases that are obtained from Bacillus lentus are preferably used. Here, mixtures of enzymes are of particular interest, for example, proteases and amylases or proteases and lipases or lipolytic enzymes or proteases and cellulases or cellulases and lipase or lipolytic enzymes or proteases, amylases and lipases or lipolytic enzymes or proteases, lipases or lipolytic enzymes and cellulases, in particular, however proteases and/or lipase-containing mixtures or mixtures with lipolytic enzymes. Examples of such lipolytic enzymes are the known cutinases. Peroxidases or oxidases have also proved to be suitable in certain cases. The suitable amylases particularly include .alpha.-amylases, iso-amylases, pullulanases and pectinases. Cellobiohydrolases, endoglucanases and .beta.-glucosidases or mixtures thereof, which are also known as cellobiases, are preferred cellulases. As the different cellulase types differ in their CMCase and avicelase activities, the required activities can be adjusted by controlled mixtures of the cellulases. The content of the enzymes or enzyme mixtures may be, for example, about 0.1 to 5% by weight and is preferably 0.1 to about 3% by weight.

Builders

Zeolites. Fine crystalline, synthetic zeolites containing bound water can be used as builders, for example, preferably zeolite A and/or P. Zeolite MAP® (commercial product of the Crosfield company), is particularly preferred as the zeolite P. However, zeolite X and mixtures of A, X, Y and/or P are also suitable. A co-crystallized sodium/potassium aluminum silicate from Zeolite A and Zeolite X, which is available as Vegobond® RX. (commercial product from Condea Augusta S.p.A.), is also of particular interest. Preferably, the zeolite can be used as a spray-dried powder. For the case where the zeolite is added as a suspension, this can comprise small amounts of nonionic surfactants as stabilizers, for example, 1 to 3 wt. %, based on the zeolite, of ethoxylated C₁₂-C₁₈ fatty alcohols with 2 to 5 ethylene oxide groups, C₁₂-C₁₄ fatty alcohols with 4 to 5 ethylene oxide groups or ethoxylated isotridecanols. Suitable zeolites have an average particle size of less than 10 μm (test method: volumetric distribution Coulter counter) and preferably comprise 18 to 22 wt. %, particularly 20 to 22 wt. % of bound water. Apart from this, phosphates can also be used as builders.

Layered silicates. Suitable substitutes or partial substitutes for phosphates and zeolites are crystalline, layered sodium silicates. These types of crystalline layered silicates are described, for example, in European Patent Application EP 0164514 A1. Preferred crystalline layered silicates are those obtained for example, from the process described in International Patent Application WO 91/08171 A1.

Amorphous silicates. Preferred builders also include amorphous sodium silicates with a modulus (Na₂O:SiO₂ ratio) of 1:2 to 1:3.3, preferably 1:2 to 1:2.8 and more preferably 1:2 to 1:2.6, which dissolve with a delay and exhibit multiple wash cycle properties. The delay in dissolution compared with conventional amorphous sodium silicates can have been obtained in various ways, for example, by surface treatment, compounding, compressing/compacting or by over-drying. In the context of this invention, the term “amorphous” also means “X-ray amorphous”. In other words, the silicates do not produce any of the sharp X-ray reflexions typical of crystalline substances in X-ray diffraction experiments, but at best one or more maxima of the scattered X-radiation, which have a width of several degrees of the diffraction angle. However, particularly good builder properties may even be achieved where the silicate particles produce indistinct or even sharp diffraction maxima in electron diffraction experiments. This is to be interpreted to mean that the products have microcrystalline regions between 10 and a few hundred nm in size, values of up to at most 50 nm and especially up to at most 20 nm being preferred. This type of X-ray amorphous silicates, which similarly possess a delayed dissolution in comparison with the customary water glasses, are described, for example, in German Patent Application DE 4400024 A1. Compacted/densified amorphous silicates, compounded amorphous silicates and over dried X-ray-amorphous silicates are particularly preferred.

Phosphates. Also the generally known phosphates can also be added as builders, in so far that their use should not be avoided on ecological grounds. The sodium salts of the orthophosphates, the pyrophosphates and especially the tripolyphosphates are particularly suitable. Their content is generally not more than 25 wt. %, preferably not more than 20 wt. %, each based on the finished composition. In some cases it has been shown that particularly tripolyphosphates, already in low amounts up to maximum 10 wt. %, based on the finished composition, in combination with other builders, lead to a synergistic improvement of the secondary washing power. Preferred amounts of phosphates are under 10 wt. %, particularly 0 wt. %.

Co-Builders

Polycarboxylic acids. Useful organic cobuilders are, for example, the polycarboxylic acids usable in the form of their sodium salts of polycarboxylic acids, wherein polycarboxylic acids are understood to be carboxylic acids that carry more than one acid function. These include, for example, citric acid, adipic acid, succinic acid, glutaric acid, malic acid, tartaric acid, maleic acid, fumaric acid, sugar acids, aminocarboxylic acids, nitrilotriacetic acid (NTA) and its derivatives and mixtures thereof. Preferred salts are the salts of polycarboxylic acids such as citric acid, adipic acid, succinic acid, glutaric acid, tartaric acid, sugar acids and mixtures thereof.

Organic acids. Acids per se can also be used. Besides their building effect, the acids also typically have the property of an acidifying component and, hence also serve to establish a relatively low and mild pH in detergents or cleansing compositions. Citric acid, succinic acid, glutaric acid, adipic acid, gluconic acid and any mixtures thereof are particularly mentioned in this regard. Further suitable acidifiers are the known pH regulators such as sodium hydrogen carbonate and sodium hydrogen sulfate.

Polymers. Particularly suitable polymeric cobuilders are polyacrylates, which preferably have a molecular weight of 2,000 to 20,000 g/mol. By virtue of their superior solubility, preferred representatives of this group are again the short-chain polyacrylates, which have molecular weights of 2,000 to 10,000 g/mol and, more particularly, 3,000 to 5,000 g/mol. Suitable polymers can also include substances that consist partially or totally of vinyl alcohol units or its derivatives.

Further suitable copolymeric polycarboxylates are particularly those of acrylic acid with methacrylic acid and of acrylic acid or methacrylic acid with maleic acid. Copolymers of acrylic acid with maleic acid, which comprise 50 to 90 wt. % acrylic acid and 50 to 10 wt. % maleic acid, have proven to be particularly suitable. Their relative molecular weight, based on free acids, generally ranges from 2,000 to 70,000 g/mol, preferably 20,000 to 50,000 g/mol and especially 30,000 to 40,000 g/mol. The (co)polymeric polycarboxylates can be added either as an aqueous solution or preferably as powder. In order to improve the water solubility, the polymers can also comprise allylsulfonic acids as monomers, such as, for example, allyloxybenzene sulfonic acid and methallyl sulfonic acid as in the EP 0727448 B1.

Biodegradable polymers comprising more than two different monomer units are particularly preferred, examples being those comprising, as monomers, salts of acrylic acid and of maleic acid, and also vinyl alcohol or vinyl alcohol derivatives, as in DE 4300772 A1, or those comprising, as monomers, salts of acrylic acid and of 2-alkylallyl sulfonic acid, and also sugar derivatives. Further preferred copolymers are those that are described in German Patent Applications DE 4303320 A1 and DE 4417734 A1 and preferably include acrolein and acrylic acid/acrylic acid salts or acrolein and vinyl acetate as monomers.

Similarly, other preferred builders are polymeric aminodicarboxylic acids, salts or precursors thereof. Those polyaspartic acids or their salts and derivatives disclosed in German Patent Application DE 19540086 A1 as having a bleach-stabilizing action in addition to cobuilder properties are particularly preferred.

Further suitable builders are polyacetals that can be obtained by treating dialdehydes with polyol carboxylic acids that possess 5 to 7 carbon atoms and at least 3 hydroxyl groups, as described in European Patent Application EP 0280223 A1. Preferred polyacetals are obtained from dialdehydes like glyoxal, glutaraldehyde, terephthalaldehyde as well as their mixtures and from polycarboxylic acids like gluconic acid and/or glucoheptonic acid.

Carbohydrates. Further suitable organic cobuilders are dextrins, for example, oligomers or polymers of carbohydrates that can be obtained by the partial hydrolysis of starches. The hydrolysis can be carried out using typical processes, for example, acidic or enzymatic catalyzed processes. The hydrolysis products preferably have average molecular weights in the range of 400 to 500,000 g/mol. A polysaccharide with a dextrose equivalent (DE) of 0.5 to 40 and, more particularly, 2 to 30 is preferred, the DE being an accepted measure of the reducing effect of a polysaccharide in comparison with dextrose, which has a DE of 100. Both maltodextrins with a DE between 3 and 20 and dry glucose syrups with a DE between 20 and 37 and also so-called yellow dextrins and white dextrins with relatively high molecular weights of 2,000 to 30,000 g/mol may be used. A preferred dextrin is described in British Patent Application 94 19 091.

The oxidized derivatives of such dextrins concern their reaction products with oxidizing compositions that are capable of oxidizing at least one alcohol function of the saccharide ring to the carboxylic acid function. Such oxidized dextrins and processes for their manufacture are known for example, from European Patent Applications EP 0232202 A1. A product oxidized at C6 of the saccharide ring can be particularly advantageous.

Oxydisuccinates and other derivatives of disuccinates, preferably ethylenediamine disuccinate are also further suitable cobuilders. Here, ethylene diamine-N,N′-disuccinate (EDDS), the synthesis of which is described for example, in U.S. Pat. No. 3,158,615, is preferably used in the form of its sodium or magnesium salts. In this context, glycerine disuccinates and glycerine trisuccinates are also particularly preferred, such as those described in U.S. Pat. No. 4,524,009. Suitable addition quantities in zeolite-containing and/or silicate-containing formulations range from 3 to 15% by weight.

Lactones. Other useful organic co-builders are, for example, acetylated hydroxycarboxylic acids and salts thereof which optionally may also be present in lactone form and which contain at least 4 carbon atoms, at least one hydroxyl group and at most two acid groups. Such cobuilders are described, for example, in International Patent Application WO 95/20029 A1.

Soil Repellents

In addition, the compositions can also comprise components that positively influence the oil and fat removal from textiles during the wash (so-called soil repellents). This effect is particularly noticeable when a textile is dirty and had been previously already washed several times with an inventive detergent that comprised this oil- or fat-removing component. The preferred oil and fat removing components include, for example, nonionic cellulose ethers such as methyl cellulose and methyl hydroxypropyl cellulose with a content of methoxy groups of 15 to 30 wt. % and hydroxypropoxy groups of 1 to 15 wt. %, each based on the nonionic cellulose ether, as well as polymers of phthalic acid and/or terephthalic acid or their derivatives known from the prior art, particularly polymers of ethylene terephthalates and/or polyethylene glycol terephthalates or anionically and/or nonionically modified derivatives thereof. From these, the sulfonated derivatives of the phthalic acid polymers and the terephthalic acid polymers are particularly preferred.

Inorganic Salts

Further suitable ingredients of the composition are water-soluble inorganic salts such as bicarbonates, carbonates, amorphous silicates or mixtures of these; alkali carbonate and amorphous silicate are particularly used, principally sodium silicate with a molar ratio Na₂O:SiO₂ of 1:1 to 1:4.5, preferably of 1:2 to 1:3.5. Preferred compositions comprise alkaline salts, builders and/or cobuilders, preferably sodium carbonate, zeolite, crystalline, layered sodium silicates and/or trisodium citrate, in amounts of 0.5 to 70 wt. %, preferably 0.5 to 50 wt. %, particularly 0.5 to 30 wt. % anhydrous substance.

Foam Inhibitors

Especially when used in automatic washing processes, it can be advantageous to add conventional foam inhibitors to the compositions. Suitable foam inhibitors include for example, soaps of natural or synthetic origin, which have a high content of C₁₈-C₂₄ fatty acids. Suitable non-surface-active types of foam inhibitors are, for example, organopolysiloxanes and mixtures thereof with microfine, optionally silanised silica and also paraffins, waxes, microcrystalline waxes and mixtures thereof with silanised silica or bis-stearyl ethylenediamide. Mixtures of various foam inhibitors, for example, mixtures of silicones, paraffins or waxes, are also used with advantage. Preferably, the foam inhibitors, especially silicone-containing and/or paraffin-containing foam inhibitors, are loaded onto a granular, water-soluble or dispersible carrier material. Especially in this case, mixtures of paraffins and bis-stearylethylene diamides are preferred.

Sequestrants

The salts of polyphosphonic acid can be considered as sequestrants or as stabilizers, particularly for peroxy compounds and enzymes, which are sensitive towards heavy metal ions. Here, the sodium salts of, for example, 1-hydroxyethane-1,1-diphosphonate, diethylenetriamine pentamethylene phosphonate or ethylenediamine tetramethylene phosphonate are used in amounts of 0.1 to 5 wt. %.

Graying Inhibitors

Graying inhibitors have the function of maintaining the dirt that was removed from the fibers suspended in the washing liquor, thereby preventing the dirt from resettling. Water-soluble colloids of mostly organic nature are suitable for this, for example, the water-soluble salts of (co)polymeric carboxylic acids, glue, gelatins, salts of ether carboxylic acids or ether sulfonic acids of starches or celluloses, or salts of acidic sulfuric acid esters of celluloses or starches. Water-soluble, acid group-containing polyamides are also suitable for this purpose. Moreover, soluble starch preparations and others can be used as the above-mentioned starch products, e.g., degraded starches, aldehyde starches etc. Polyvinyl pyrrolidone can also be used. Preference, however, is given to the use of cellulose ethers such as carboxymethyl cellulose (Na salt), methyl cellulose, hydroxyalkyl celluloses and mixed ethers such as methyl hydroxyethyl cellulose, methyl hydroxypropyl cellulose, methyl carboxymethyl cellulose and mixtures thereof, as well as polyvinyl pyrrolidone, which can be added, for example, in amounts of 0.1 to 5 wt. %, based on the composition.

Optical Brighteners and UV Adsorbers

The compositions may comprise e.g., derivatives of diaminostilbene disulfonic acid or alkali metal salts thereof as the optical brighteners. Suitable optical brighteners are, for example, salts of 4,4′-bis-(2-anilino-4-morpholino-1,3,5-triazinyl-6-amino)stilbene-2,2′-di-sulfonic acid or compounds of similar structure which contain a diethanolamino group, a methylamino group, an anilino group or a 2-methoxyethylamino group instead of the morpholino group. Brighteners of the substituted diphenylstyryl type may also be present, for example, the alkali metal salts of 4,4′-bis(2-sulfostyryl)diphenyl, 4,4′-bis(4-chloro-3-sulfostyryl)diphenyl or 4-(4-chlorostyryl)-4′-(2-sulfostyryl)diphenyl. Mixtures of the mentioned brighteners may also be used.

In addition, UV absorbers may also be added. These are compounds with distinct absorption abilities for ultra violet radiation, which contribute as UV stabilizers as well as to improve the light stability of colorants and pigments both for textile fibers as well as for the skin of the wearer of textile products by protecting against the UV radiation that penetrates the fabric. In general, the efficient radiationless deactivating compounds are derivatives of benzophenone, substituted with hydroxyl and/or alkoxy groups, mostly in position(s) 2 and/or 4. Also suitable are substituted benzotriazoles, additionally acrylates that are phenyl-substituted in position 3 (cinnamic acid derivatives), optionally with cyano groups in position 2, salicylates, organic Ni complexes, as well as natural substances such as umbelliferone and the endogenous urocanic acid. In a preferred embodiment, the UV absorbers absorb UV-A and UV-B radiation as well as possible UV-C radiation and re-emit light with blue wavelengths, such that they additionally have an optical brightening effect. Preferred UV absorbers encompass triazine derivatives, e.g., hydroxyaryl-1,3,5-triazine, sulfonated 1,3,5-triazine, o-hydroxyphenylbenzotriazole and 2-aryl-2H-benzotriazole as well as bis(anilinotriazinyl-amino)stilbene disulfonic acid and their derivatives. Ultra violet absorbing pigments like titanium dioxide can also be used as UV absorbers.

Thickeners

The compositions can also comprise common thickeners and anti-deposition compositions as well as viscosity regulators such as polyacrylates, polycarboxylic acids, polysaccharides and their derivatives, polyurethanes, polyvinyl pyrrolidones, castor oil derivatives, polyamine derivatives such as quaternized and/or ethoxylated hexamethylenediamines as well as any mixtures thereof. Preferred compositions have a viscosity below 10,000 mPa*s, measured with a Brookfield viscosimeter at a temperature of 20° C. and a shear rate of 50 min⁻¹.

Perfumes and Colorants

The compositions can comprise further typical detergent and cleansing composition ingredients such as perfumes and/or colorants, wherein such colorants are preferred that leave no or negligible coloration on the fabrics being washed. Preferred amounts of the totality of the added colorants are below 1 wt. %, preferably below 0.1 wt. %, based on the composition. The compositions can also comprise white pigments such as e.g., TiO₂.

Food Compositions

Another embodiment of the present invention covers a food composition comprising a working amount of at least one acetophenone derivative or its mixtures with additional preservatives and/or antimicrobial agents, which might be present in amounts of from about 0.01 to about 10, preferably about 0.05 to about 5 and more preferably about 0.1 to about 1% b.w.—calculated on the total composition.

Food compositions according to the invention are any preparations or compositions which are suitable for consumption and are used for nutrition or enjoyment purposes, and are generally products which are intended to be introduced into the human or animal oral cavity, to remain there for a certain time and then either be eaten (e.g. ready-to-eat foodstuffs or feeds, see also herein below) or removed from the oral cavity again (e.g. chewing gums). Such products include any substances or products which in the processed, partially processed or unprocessed state are to be ingested by humans or animals. They also include substances which are added to orally consumable products during their manufacture, preparation or treatment and which are intended to be introduced into the human or animal oral cavity.

The food compositions according to the invention also include substances which in the unchanged, treated or prepared state are to be swallowed by a human or animal and then digested; in this respect, the orally consumable products according to the invention also include casings, coatings or other encapsulations which are to be swallowed at the same time or which may be expected to be swallowed. The expression “orally consumable product” covers ready-to-eat foodstuffs and feeds, that is to say foodstuffs or feeds that are already complete in terms of the substances that are important for the taste. The expressions “ready-to-eat foodstuff” and “ready-to-eat feed” also include drinks as well as solid or semi-solid ready-to-eat foodstuffs or feeds. Examples which may be mentioned are frozen products, which must be thawed and heated to eating temperature before they are eaten. Products such as yoghurt or ice-cream as well as chewing gums or hard caramels are also included among the ready-to-eat foodstuffs or feeds.

Preferred food compositions according to the invention also include “semi-finished products”. Within the context of the present text, a semi-finished product is to be understood as being an orally consumable product which, because of a very high content of flavourings and taste-imparting substances, is unsuitable for use as a ready-to-eat orally consumable product (in particular foodstuff or feed). Only by mixing with at least one further constituent (e.g. by reducing the concentration of the flavourings and taste-imparting substances in question) and optionally further process steps (e.g. heating, freezing) is the semi-finished product converted into a ready-to-eat orally consumable product (in particular foodstuff or feed). Examples of semi-finished products which may be mentioned here are

Methods for Preservation and Fighting Body Odor

The acetophenone derivatives and the respective mixtures according to the invention display their synergistically intensified antimicrobial action against a large number of Gram-positive bacteria, Gram-negative bacteria, moulds and yeasts, which in particular renders possible preservation and antimicrobial treatment of a large number of cosmetic formulations. A particularly good action exists against Gram-positive bacteria, such as Staphylococcus aureus, Staphylococcus epidermidis, Corynebacterium xerosis, and Propionibacterium acnes, against Gram-negative bacteria, such as Escherichia coli and Pseudomonas aeruginosa, against yeasts, such as Candida albicans, Malassezia furfur and globosa, and precisely—as already mentioned—against fungi, such as mould species of the genus Aspergillus and others. The very good activity of the mixtures according to the invention against moulds of the genus Aspergillus, a fungal group, which can be combated only with great difficulty, is to be regarded as particularly advantageous here.

Therefore, another object of the present invention relates to a method for preserving a personal care composition, a detergent composition or a food composition by adding a working amount of at least one acetophenone derivative or its mixture with a second preservative or an antimicrobial agent.

Another object of the present invention refers to a method for fighting micro-organisms by adding a working amount of at least one acetophenone derivative or its mixture with a second preservative or an antimicrobial agent to a personal care, detergent or food composition.

The invention covers also the use of at least one acetophenone derivative or its mixture with a second preservative or an antimicrobial agent as a preservative, in particular for personal care, detergent or food compositions, preferably in amounts of from about 0.01 to about 10, preferably about 0.05 to about 5 and more preferably about 0.1 to about 1% b.w.

Another object of the present invention refers to a method for fighting micro-organisms by adding a working amount of at least one acetophenone derivative or its mixture with a second preservative or an antimicrobial agent.

The acetophenone derivatives and their mixtures are particularly useful against microorganisms which cause body odour, acne and/or mycoses. Advantageously, the preservatives or preservative mixtures are applied to human skin at concentrations of 0.01 to about 10, preferably about 0.05 to about 5 and more preferably about 0.1 to about 1% b.w. in each case based on the total weight of the cosmetic or pharmaceutical product which comprises the mixture. The synergistically active mixtures can be employed here (a) prophylactically or (b) as required. The concentration of the amount of active compound to be applied e.g. daily varies and depends on the physiological state of the subject and individual-specific parameters, such as age or body weight. The synergistically active mixtures according to the invention can be employed either by themselves or in combination with further antimicrobically active substances.

Another object of the present invention therefore covers a method for treating unpleasant body odour, in particular underarm and foot odour by topical administration a working amount of at least one acetophenone derivative or its mixture with a second preservative or an antimicrobial agent to the skin. Finally, the invention refers to the use of at least one acetophenone derivative or its mixture with a second preservative or an antimicrobial as a deodorant.

It is understood that the explanations and preferred embodiments outlined above with respect to the acetophenone derivatives and their mixtures mutatis-mutandis apply also for the methods and uses as claimed, thus no additional repetition is necessary.

EXAMPLES Example 1

Synergistic activity of 4-hydroxyacetophenone in combination with various secondary antimicrobial agents against the microorganism A. brasiliensis was determined. To calculate the synergism between compounds of formula (I) and other antimicrobial actives, the Kull equation¹ ² was used

SI=(C _(mixture) ×P _(A))/C _(A)+(C _(mixture) ×P _(B))/C _(B)  (I)

where SI is the Synergy Index according to Kull^(1), 2)) C_(A) is the cell count for substance A C_(B) is the cell count for substance B C_(mixture) is the cell count for the mixture of substances A and B P_(A) is the proportion of the substance A in the mixture P_(B) is the proportion of the substance B in the mixture. ¹ Kull, F. C., Eismann, P. C., Sylvestrowicz, H. D., and R. L. Mayer (1961). Mixtures of Quaternary Ammonium Compounds and Long-chain Fatty Acids as Antifungal Agents. Applied Microbiology 9, 538-541.² Steinberg, D. C. (2000). Measuring Synergy. Cosmetics & Toiletries 115 (11), 59-62.

Antimicrobil activity was evaluated by determining the Minimum Inhibitory Concentration (MIC) representing the lowest concentration of a chemical which prevents visible growth of a bacterium.

The MIC values were determined by preparing solutions of the chemical in vitro at increasing concentrations, incubating the solutions with the separate batches of cultured bacteria, and measuring the results using agar dilution or broth microdilution. Results have been graded into susceptible (often called sensitive), intermediate, or resistant to a particular antibiotic by using a cutoff point. Cut off points are agreed upon values, published in guidelines of a reference body, such as the U.S. Clinical and Laboratory Standards Institute (CLSI), the British Society for Antimicrobial Chemotherapy (BSAC) or the European Committee on Antimicrobial Susceptibility Testing (EUCAST).
